WEA series slewing drive,slew drive is a new series of slewing product, also named as slewing reducer. It is commonly composed of worm, slewing bearing, housing, motor adapter, end cap and other components. By adopting slewing bearing as its core component, slewing drive can bear axial force, radial force and tilting moment simultaneously. Comparing with SE series slewing drive, WEA series have the advantages of better protective performance, great transmission torque, better impact resistance and long working life.
WEA series slewing drive is widely applied in the relatively rotary parts of machinery and solar energy field. Solar tracking system Rotary chassis of aerial working machinery Truck crane Rock drill, drilling machine Grasping wood machine, code molding machine.
Robotic arms are mechanical devices that have joints that can bend and rotate. They are driven by computer-controlled electric motors. Tools can be fitted to the 'hand' end of the arms, and the computer programmed to make them perform different tasks, such as cutting, drilling, welding, and painting. They are also used for dangerous tasks such as handling radioactive materials or unexploded bombs.
Applications:
Typical slewing drive applications include but are not limited to:Solar trackers,wind turbines,Man lifts,Hydraulic Machinery, Telescopic Handlers, Digger Derricks, Lifts, Cranes, Drilling equipment, Military Equipment
